The discussion focuses on calculating the electric potential at points a and b due to two charges, Q1 = +1.60 nC and Q2 = -1.60 nC. The correct formula used is V = kQ/r, where k is Coulomb's constant (8.99e9 N m²/C²). The initial calculation yielded an incorrect potential of 191700 V due to a numerical error in the conversion of nanocoulombs. The correct interpretation of nanocoulombs as x10-9 is crucial for accurate results.

Find the potential at points a and b in the diagram for charges Q1 = +1.60 nC and Q2 = -1.60 nC.
I know b is 0
Homework Equations
V = kQ/r
The Attempt at a Solution
I tried this using the equation and got
8.99e9 * [( +1.60e-6 / .05) + ( -1.60e-6 / .15 ) ] = 191700 V but this isn't right any suggestions??
